Description

Technical Field

[0001] The utility model relates to the technical field of silicone rubber production, in particular to a cooling device for silicone rubber production. Background Art

[0002] Silicone rubber is a material similar to ointment that will solidify into a tough rubber-like solid once it comes into contact with moisture in the air. It is a high-performance adhesive with excellent properties and is widely used in the fields of construction, electronics, automobiles, etc. Its production process generally includes steps such as raw material formulation, mixing, dissolution, homogenization, filling, and curing. During the process of mixing and stirring the raw materials, they are pushed into a multi-functional disperser for stirring and high-speed dispersion. The high temperature generated in this way will affect the quality of the silicone rubber. Therefore, after the stirring is completed, the raw materials need to be cooled to control the temperature of the raw materials and ensure the production quality of the silicone rubber.

[0003] However, the existing cooling system in silicone rubber production is not perfect enough. Affected by the discharging speed of the raw materials, if the discharging speed is too fast, it may cause insufficient cooling of the raw materials; the existing silicone rubber cooling equipment usually uses a round pipe on the outer side of the feeding pipe, so the cooling area is limited; the cooling pipe inside the feeding pipe of the existing silicone rubber cooling equipment has a small flow rate and is located at the inner center position of the raw materials, which easily leads to insufficient heat transfer coefficient of the internal cooling water, poor cooling efficiency, and the need to extend the cooling time, which is time-consuming and laborious. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cooling device for silicone rubber production, which can effectively improve the situation of insufficient cooling of the raw materials for silicone rubber production and improve the cooling rate.

[0005] To achieve the above purpose, the utility model provides the following scheme:

[0006] A cooling device for silicone rubber production includes a feeding pipe, a cooling pipe, and a cooling cylinder. The feeding pipe and the cooling pipe are arranged inside the cooling cylinder. The feeding pipe includes a feeding port, a pipe body, and a discharging port. The bottom end of the feeding port is welded to the top end of the pipe body. The front view of the feeding port is an isosceles trapezoid. The radius of the bottom end of the feeding port is equal to the radius of the pipe body, and the radius of the top end of the feeding port is greater than the radius of the pipe body. The bottom end of the pipe body is welded with a discharging port, and the discharging port is in a "funnel" shape. The cooling pipe includes a spiral square pipe and a spiral circular pipe. The spiral square pipe is arranged between the feeding pipe and the cooling cylinder. The spiral square pipe is spirally fixed on the outer side of the pipe body, and the inner side surface of the spiral square pipe is closely attached to the outer side surface of the pipe body. The spiral circular pipe is suspended inside the pipe body. Both ends of the spiral circular pipe and the spiral square pipe pass through the cooling pipe and the cooling cylinder and are connected to a water supply interface outside the equipment.

[0007] Further, through holes are provided at both the upper and lower ends of the pipe body and the cooling cylinder. The straight pipe portions of the spiral square pipe and the spiral circular pipe are connected to the water supply interface outside the device through the through holes, and the spiral portions of the spiral square pipe and the spiral circular pipe are both arranged inside the device.

[0008] Further, the spiral square pipe is connected with an input pipe and an output pipe. The input pipe and the output pipe are respectively flange-connected to both ends of the spiral square pipe. The input pipe is arranged near the feeding port end, and the output pipe is arranged near the discharging port end.

[0009] Further, the spiral circular pipe includes an input port, a pressure pump, and an output port. The input port is arranged at the upper end of the spiral circular pipe. The input port is connected to the spiral circular pipe through the pressure pump. The pressure pump is flange-connected to the upper end of the spiral circular pipe, and an output port is arranged at the lower end of the spiral circular pipe.

[0010] Further, the cooling cylinder includes a cylinder body, a sealing plate, and a through hole.

The feeding port and the discharging port respectively pass through the upper and lower sealing plates. The sealing plates are welded to the outside of the material conveying pipe, and the material conveying pipe and the cooling cylinder are connected through the sealing plates.

[0011] In summary, the beneficial technical effects of the present utility model are as follows:

[0012] 1. The discharging port is arranged in a funnel shape, reducing the discharging speed of the silicone rubber raw material, so that the silicone rubber raw material can be cooled more sufficiently;

[0013] 2. The spiral square pipe is adopted, increasing the contact area between the outer wall of the material conveying pipe and the cooling pipe, and enhancing the cooling effect;

[0014] 3. The pressure pump is selected, increasing the flow rate of the cooling water in the spiral circular pipe and ensuring the cooling effect inside the material conveying pipe. Description of the Drawings

[0019] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0020] For cooling, the feeding pipe 1 includes a feeding port 11, a pipe body 12, and a discharging port 13. The bottom end of the feeding port 11 is welded to the top end of the pipe body 12. The front view of the feeding port 11 is an isosceles trapezoid. The radius of the bottom end of the feeding port 11 is equal to the radius of the pipe body 12, and the radius of the top end of the feeding port 11 is greater than the radius of the pipe body 12. This shape facilitates feeding. The bottom end of the pipe body 12 is welded with a discharging port 13, and the discharging port 13 is in the shape of a "funnel". This shape reduces the discharging speed of the silicone rubber raw material and prolongs the cooling time of the raw material, enabling the raw material to obtain a more sufficient cooling effect. Through holes 33 are provided at both the upper and lower ends of the pipe body 12 and the cooling cylinder 3. The straight part of the cooling pipe 2 is connected to a water inlet interface outside the device through the through hole 33, and the through hole 33 is welded and sealed with the cooling pipe 2. The spiral part of the cooling pipe 2 is arranged inside the device. The cooling cylinder 3 includes a cylinder body 31, a sealing plate 32, and a through hole 33. Sealing plates 32 are welded to both the upper and lower ends of the cylinder body 31. The feeding port 11 and the discharging port 13 respectively pass through the upper and lower sealing plates 32. The sealing plates 32 are welded to the outside of the feeding pipe 1. The sealing plates 32 seal between the feeding pipe 1 and the cooling cylinder 3. The feeding pipe 1 and the cooling cylinder 3 are connected through the sealing plates 32. The sealing plates 32 seal between the feeding pipe 1 and the cooling cylinder 3, isolating the cooling part of the cooling pipe 2 from the external air, preventing the cooling pipe 2 from being affected by the external air in terms of heat exchange effect, and ensuring the cooling effect of the raw material. See specifically Figure 1 、 Figure 2 。

[0021] The part of the cooling pipe 2 for cooling the raw materials is spiral. The spiral cooling pipe 2 has the characteristics of compact structure, larger heat transfer area than straight pipes, and small temperature difference stress, achieving efficient heat exchange in a limited space and improving the cooling efficiency. The cooling pipe 2 includes a spiral square pipe 21 and a spiral round pipe 22. The spiral square pipe 21 is arranged between the material conveying pipe 1 and the cooling cylinder 3. The spiral square pipe 21 is spirally fixed on the outer side of the pipe body 12. The inner side surface of the spiral square pipe 21 closely adheres to the outer side surface of the pipe body 12, and the outer side surface of the spiral square pipe 21 closely adheres to the inner wall of the cylinder body 31. Since the square pipe spirals to form a cylindrical tube, the outer wall of the material conveying pipe 1 fits with the cooling pipe 2, increasing the contact area between the outer wall of the material conveying pipe 1 and the cooling pipe 2 and enhancing the cooling effect. The spiral round pipe 22 is suspended in the pipe body 12 and directly contacts the raw materials. The two ends of the spiral round pipe 22 and the spiral square pipe 21 pass through the cooling pipe 2 and the cooling cylinder 3 and are connected to the water supply interface outside the equipment, and the cooling water circulates through the water supply interface. The spiral square pipe 21 is connected with an input pipe 211 and an output pipe 212. The input pipe 211 and the output pipe 212 are respectively flange-connected to the two ends of the spiral square pipe 21. The input pipe 211 is arranged at the end close to the feeding port 11, and the output pipe 212 is arranged at the end close to the discharging port. The output pipe 212 and the input pipe 211 are circular tubes. Since the water supply interface outside the equipment is usually circular, the circular tube is convenient for connecting the water supply interface outside the equipment. The spiral round pipe 22 includes an input port 221, a pressure pump 222, and an output port 223. The input port 221 is arranged at the upper end of the spiral round pipe 22. Since the spiral round pipe 22 is relatively thin and located inside the material conveying pipe 1 and directly contacts the high-temperature raw materials, a pressure pump 222 is added. The input port 221 is connected to the spiral round pipe 22 through the pressure pump 222. The pressure pump 222 is flange-connected to the upper end of the spiral round pipe 22. By means of the pressure pump 222, the flow rate of the cooling water from the input port 221 into the pipe is increased, ensuring the cooling effect of the raw materials inside the material conveying pipe 1. The output port 223 is arranged at the lower end of the spiral round pipe 22. See specifically Figure 3 。
